Abstract
A printing device comprising a stencil printing device which is excellent in operativity, in which a print drum with UV ink and non-UV ink can be used in a single stencil printing device. The printing device has a stencil printing control device and UV irradiation control device in which a drum unit ink type identifying sensor, which detects whether the print drum attached to the stencil printing device main body is a print drum unit for UV ink or a drum unit for non-UV ink, is used to operate at least a UV lamp, of the UV lamp and a UV auxiliary lamp, and to irradiate UV light when attachment of the drum unit for UV ink is detected, or to stop the operation of the UV lamp and UV auxiliary lamp when attachment of the print drum unit for non-UV ink is detected.
Claims22
A printing device, comprising:
- ultraviolet irradiation means for irradiating a printed paper with ultraviolet radiation;
- attaching/detaching means for selectively attaching and detaching to and from a printing device main body a print drum for ultraviolet curable ink, installed with an ultraviolet curable ink, and a print drum for non-ultraviolet curable ink, installed with a non-ultraviolet curable ink;
- print drum detection means for detecting whether the print drum attached to the printing device main body via the attaching/detaching means is either the print drum for ultraviolet curable ink or the print drum for non-ultraviolet curable ink;
- and
- first control means for operating the ultraviolet irradiation means when attachment of the print drum for ultraviolet curable ink is detected by the print drum detection means, and stopping the operation of the ultraviolet irradiation means when attachment of the print drum for non-ultraviolet curable ink is detected by the print drum detection means.
An ultraviolet irradiation apparatus capable of being connected to the printing device, the ultraviolet irradiation apparatus comprising:
- ultraviolet irradiation means for irradiating a printed paper with ultraviolet radiation;
- paper conveying means for conveying the printed paper to be irradiated with the ultraviolet radiation;
- and
- control means for operating the ultraviolet irradiation means on the basis of a signal transmitted from the printing device indicating that a print drum for ultraviolet curable ink installed with an ultraviolet curable ink has been attached, and for stopping the operation of the ultraviolet irradiation means on the basis of a signal transmitted from the printing device indicating that a print drum for non-ultraviolet curable ink installed with a non-ultraviolet curable ink has been attached.
A printing device, comprising:
- an ultraviolet irradiation device configured to irradiate a printed paper with ultraviolet radiation;
- an attaching/detaching device configured to selectively attach and detach to and from a printing device main body a print drum for ultraviolet curable ink, installed with an ultraviolet curable ink, and a print drum for non-ultraviolet curable ink, installed with a non-ultraviolet curable ink;
- a print drum detection-device configured to detect whether the print drum attached to the printing device main body via the attaching/detaching device is either the print drum for ultraviolet curable ink or the print drum for non-ultraviolet curable ink;
- and
- a first control device configured to operate the ultraviolet irradiation device when attachment of the print drum for ultraviolet curable ink is detected by the print drum detection device, and stopping the operation of the ultraviolet irradiation device when attachment of the print drum for non-ultraviolet curable ink is detected by the print drum detection device.
An ultraviolet irradiation apparatus capable of being connected to the printing device, the ultraviolet irradiation apparatus comprising:
- an ultraviolet irradiation device configured to irradiate a printed paper with ultraviolet radiation;
- a paper conveying device configured to convey the printed paper to be irradiated with the ultraviolet radiation;
- and
- a control device configured to operate the ultraviolet irradiation device on the basis of a signal transmitted from the printing device indicating that a print drum for ultraviolet curable ink installed with an ultraviolet curable ink has been attached, and for stopping the operation of the ultraviolet irradiation devise on the basis of a signal transmitted from the printing device indicating that a print drum for non-ultraviolet curable ink installed with a non-ultraviolet curable ink has been attached.
